How much Caffeine is in Your coffee?

Coffee – Many stop on their way into work each morning and pick up a cup of coffee. How much caffeine are we getting when we do that? It varies. A lot.

BuzzFeed commissioned a study to see how much caffeine was in coffee from some of the most frequent stops (Starbucks, 7-Eleven, McDonald’s and Dunkin Donuts). Samples were taken from shops in New York City and in San Francisco.

First, their results showed that East Coast coffee is stronger, on average, than West Coast coffee. The other surprising outcome was that 7-Eleven coffee had the most (280 mg) caffeine. All the samples were medium cups of coffee and black (the way coffee should always be consumed in my opinion). For those of you who are Starbuck’s fans, their coffee came in second (267 mg) in caffeine strength.

Just to put that in perspective, a report in the journal Food and Chemical Toxicology has says that a healthy adult can safely consume up to 400 mg of caffeine per day. The FDA says that the average American consumes about 300 mg of caffeine a day.
